First of all check your RAM, display problem is mostly due to RAM. Try this RAM in any other computer, if it is working there, then two options are there

Your graphic card is expired or not configured properly. If you replaced graphic card in recently, check that it is properly attached to the port. If your computer have external graphic card then check it in someone else computer.

You said that when you press F2 button, computer gives response, it means that graphic card is not processing and not sending output to monitor. Or it is sending output to monitor but monitor cable have some problems and unable to display results.

You mentioned you replaced the power supply and it works fine. The last computer I handled is a bit similar to yours. With so many things I suspected, I ended up replacing the memory. Try to swap a different memory and hopefully it will work just fine. If the memory replacement cannot solve your problem, it may be the last things to be broken but sometimes, they broke. The component I am talking about is the motherboard and the processor.

If you have some spare component to use, you may try to swap them up to your unit. You may experience inconvenience but it will give you the security that the component you are going to buy is the real defective ones.

Dear Frail

According to you, all the BIOS and drives are working well, but still your computer is still not starting. There are two reasons why it happens. First, is because of your motherboard, just like with my other computer, it doesn't start, so I decided to have a system check up and bring it to the technical expert, and it only finds out that the motherboard was the problem of my system unit, so the technician change the motherboard.

But even if he change it, still, has same result, so he change the CPU or the central processing unit, then it was worked. So, primarily, your problem may in this two reasons.
